Petalite Cleavage
When it comes to choosing the best pick among Gems Found In Australia gemstones, Petalite is known to be a popular choice!Physical properties of Petalite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Petalite Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Petalite cleavage is nothing but the plane across which the crystal splits during cutting. Petalite cleavage is Perfect on , poor on with 38.5° angle between the two,and specific gravity of Petalite is 2.40.
The physical properties of Petalite, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Petalite is represented by LiAlSi 4O 10Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
